Key legal question
Whether the complaint against the interlocutory decision was admissible under Art. 93(1)(b) BGG
Extracted holding
The appellant did not sufficiently show that immediate review of the interlocutory decision would avoid a significant amount of time and costs in a wide-ranging evidentiary proceeding.
Extracted reasoning
Self-standing review of interlocutory decisions is exceptional and must be strictly construed. The burden lies on the appellant to explain concretely why Art. 93(1)(b) BGG is met. Here, the file and the judgment did not show that a major evidentiary effort would be spared.
